Thanks for the information,


Is 6-10 ppm chlorine in a non-stabilized indoor pool a shock level for algae removal... or what is the shock ppm level on a non-CYA pool?

Is a Borax level of 40-50 would be good for preventing algae?

Does Borax have any health concerns I need to think about?

I have a cartridge filter and Pentair says put a cup if DE in skimmer for bettering filtering. Is this a good idea?

Thanks in advance.
